It was also planned to use a tail exhaust to achieve more thrust, effectively creating a Motorjet[1][2] The proposal was filed as "Re.2005 R" by Regia Aeronautica, but remained only a paper project, as, according to Longhi, the aircraft would have had problems with its center of gravity.

[3][1] One possible alternative method of propulsion to the motorjet to was to obtain turbojet engines from Germany, but despite requests from Antonio Alessio and Count Giovanni Battista Caproni, the Germans delivered only a wooden mock-up for dimensional tests to Reggiane.

[1] After the war, Longhi tried to conduct experiments with two Junkers Jumo 004 engines that were left in Udine airport after the German defeat.

These extremely valuable jet engines were delivered to Italy in 1945 as spare parts for a Luftwaffe high speed reconnaissance flight, equipped with three Arado Ar 234 Blitz, when the nearly impossible to intercept German twin-jet planes participated in the Italian campaign.

Most modern scholars now consider the Re.2007 to not have been a real design; instead being merely a "phantom" of sorts, cobbled together from various projects by faulty recollection.
